and 4, the said holes being ci' such size` as to permit th e"watcr to ilowout through them without allowing the escupe' of the mcesblid: ccntcntsvoti the bucket. i l 1 a v f The bail or handle, by which the draught-rope is attached to the top or ouen and of vthe bucket, is shown at e, and is pivotcd at or near the centre thereof, and is plovided with a.. slot through which passes the curved bracejliixe'd upon-the aforesaid end of th body of "the 4bucket in suchmanner that by means of a sct-screw the bail may be xed thereto at any angle to the longitudinalasis of the buclchto the end that the said bail may be secured so that its forward end will be higher 'than its rear extremity when tbc bucket is drawn through the sewer, so. tl 1at the open end'of the said bucket will be inclined downward, as shown in iig. 1,1to insure the ready passage inte it of the sediment o'r leposittcbe removed. i

In yorder to'jstill further facilitate this filling of the bucket, the body@ therebf is made oval in its crossscetion, as shown more fully in iig, 3, one ofthe attened sides ofthe said body being'dowriwar'd when the bucket is drawn through the section of thel sewer, as hereinbefore indicated, t

Situated atene side ofcach manfholeaa-nd within the sewer, as shown lin iig. 1, is a pulley, g, `designed to. guide the draught-rope in operating the'buckets, andlwhich is attached td s holding-devicc, D, constructed as follows: I l

The horizontal and parallel bars l, to one end o f'which the pulleyg ispivoted, have pivoted between them,

at the ends opposite the pulley, two bars, z', t o the 'extremities ofy which are pivoted two crossedbarshg', which -are connected-at their-centres-bya transverse pin, a', the endsof which work in slots, c X, formed lengthwise in the bars.h,the several bars -being so arranged that the strain of'the draught-rope upon the pulleys g, by tending to bring the bars 'ij intoa position'more nearly'parallel with each other, forces the ends of the same against the adjacent sides o r surfaces of the sewer with a pressure prcportionedto the .strain exerted upon the pulley g, ameansn'hereby the said pulley may be quickly and conveniently secured-in place, being in' this manner secured. i l

In order-that the draught-ropemay be readily placed upon or thrown off from the pulley g; the pivot of the latter is 'attached to the device 'D only at one end, as shown more fully in ti, and to assist in guiding the draught-rope in placing the samecver the'pulley,'as hereinafter more fully explained,acurved'arm c r guide, m, is'. attached to the. aforesaid device in such manner that a passage or way is. formed, as shown at mi,

through' which therepc may be passed behind the pulley by`means. ofa hook or other suitable appliance.

-Placed at the inner side of eaclinuan-hole is a frictionAroller, mx, upon which the draught-rope runs when het upon the pulleys y, `in st mentionech I- 'l 'Placed over-each of' the two man-holes is n. horizontal frame, E, in the centre ol which is a vertical hole, e', through which the draughtrope passes, the said frames serving to so guide the rope that the buckets, in

`their yertical. ,tnvement, may `pass properiy npthreugh the manlioles. t '.lnilheI operation ofthe apparatus, that pulley g, at the man-'hole Vthroughv which itis desired to draw the buckctyhas placed over itthe. contiguous portion of the draughtlrope, andthe buckets are arranged by the m'ea'ns hereinbefcr described, atsuch distance apartthatwhcn one bucket is elevsted'above the manhole through which it passes', the cther, adjacent to the pulley 'upon whiclrtho rope'is passed, will be brought within the sewer to such distance from theother manhole as may be necessary toenable it to be filled. whendrawn for-ward, which being dene, the elevating-apparatus is operated to draw the bucket last mentioned forward, until it is brought underneath the unan-hole toward which it moves, whereupon the draught-rope is thrown, by' any suitable means, y from thelpulleyg'at the .said man-hole, whereupon the continued movement of' the vdraught-rope draws the bucketup'thbugh' the man-hole to the desired height, vthe frame being lifted by the bucket as it rises. The othei` builitb inf thehreanwhile, is brought back into the sewer through the ethcrman-holc, and-at such dis` tance-therelirom that the movement ofthe draught-rope being revcrsed,vthe said bucket'will be filled,and afterward raised in the same. manner as thc one first described; the sediment being thus removed by the alto-'rnatc action'of the two buckets, theremoval commencing at the ends of the section between themen-holes, and prgressingfinward to thecentre thereof` until completed, the length of that portion of thedraught-rope. bctwcenfthe buckets being adjusted, as hcreinhe'ore described,as may be required, to bring the 4buckets the requireddistance within the sewer at the dill'ercnt sta-ges of'the operation of removing the sediment -`therefrom, as set fortln l 4 A 'lhc 'buck-eten 'entering thew's'eigocs with its bottom downwards, and when it strikesthe sediment the leaves c c bpen inwardly and allow the body of vthe bucket to cut througlrthe sediment'as it is being drawn,vby f the rope attached to its bottom, into 'the sc\'.er,'until4it has filled with the sediment; the motion is thenyreversed, whereupon the sediment within' the bucket'causes the said leaves t'o spread, closing the bottom, andthcreby retaining its'contcnts,to be drawn out of the sewerin the "manner hcreinbeforc described. vEach time this operation is performed the buckets -may be linked closer together than at the preceding tim`c,'th us causing them to travelV farther into the section, between theV two manholos, until theyeach travolto or alittle beyond t he centre..
